3G Series Three Screw Pump
Application
It applies to deliver clean and non-corrosive medium which has lubricating troperty at temperature beow ≤150℃、with the viscosity of 5-760cSt,The pump's working pressure range from 0.6MPa to 2.5MPa and flow capacity range from 0.6-123m3/h.
Feature
(1)Medium is delivered in axial direction continuously without agitation and pulsation.
(2)Small vibration and low noise
(3)High pressure and high efficiency
(4)Simple structure,easy disassembly and assembly
(5)Small volume and lighe weight
(6)Slight wear and long life of the pump
Structure:The pumps are sealed generally by mechanical seal and driven by the motor through the claw coupling.
Material: The driving and driven screw 16MnCrS5,40Cr,45,38CrMoALA
Pump casing:HT200,QT450-10,ZCuSn10Pl,ZG270-500
